In this work, a novel inverse chiral electromagnetic band gap (EBG) structure with dual band gaps is studied. The EBG, which is made of alumina ceramic, was fabricated utilizing a 3D printing technology combining with a gel casting method. The band diagram of this EBG is simulated using a high frequency structure simulator (HFSS). Dual full band gaps of 9.2 GHz - 9.9 GHz and 10.7 GHz - 11.5 GHz that may stop the propagation of microwaves despite the directions or polarizations are found in the band diagram. As a contrast, the transmission property of the manufactured sample is measured by a transmission/reflection method. Two band gaps in accordance with the simulation are confirmed.
